Mary Wollstonecraft Shelley was born on August 30, 1797, in London to writers William Godwin and Mary Wollstonecraft. Sadly, months later her mother died of childbirth-related complications. A few years later, her father remarried, bringing two stepsiblings into the family. Feeling threatened by the beautiful Mary, her stepmother sent her to boarding school in Scotland at the age of 15.
Mary met her future husband, Percy Bysshe Shelley, that same year. She was still a child and he a married man, but two years later, his marriage was in trouble and she was older. They ran off together, and Percy encouraged Mary to write. Mary gave birth to their first child, a daughter who died two weeks after her premature birth, in 1815. Their second child, William was born the following year.
After William was born, the family of three along with Mary's stepsister Claire journeyed to Geneva to meet Lord Byron. It was there that Mary began to write her masterpiece, Frankenstein.
In 1816, both Mary's older half-sister Fanny and Percy's wife committed suicide, allowing the two to marry. Ultimately, they had four children together, but only their youngest, a boy named Percy Florence Shelley, survived to adulthood. Mary became a widow in 1822 after her husband's boat sank during a storm and was forced to provide for herself and her only living child by writing, supplemented by a small income from her father-in-law. Mary died of brain cancer on February 1, 1851, in London.
